How can i care well for the following plants in my garden (first time i've grown them)?

[Boobies]

First flat and i've gone all out this year.

I have just planted window boxes with trailing geraniums, trailing petunias and trailing fuscia. In my hanging basket and tubs i have similar things. In the ground i have a peony rose and some shrubs including a gorgeous orange blossom (That doesn't actually blossom, or at least it didn't last year, but the leaves are lovely), some heather, a clematis going up the wall and some other things i don't know the name of.
I put fish blood and bone in all the soil and have been watering them alot. I have soluable miracle grow..how often should i use that?
How quick will my baskets grow?

Your baskets should fill out really quickly.
Different feeds have different strengths so you should follow the instructions on the packet. Baskets and containers need to be fed more often. Make sure you dead head regularly, remove all the dead and dying flower heads from your petunia, geraniums, fuscia- that will encourage the plants to produce more flowers
The Heather plants should be pruned each year immediately after they have finished flowering, which results in additional flowers the following year.
A well prepared soil with good drainage is needed.
The best time to feed them is in late winter or late spring.

There's lots of types of clematis. here's a site to get you started: http://www.gardenaction.co.uk/plantfinder/clematis_1.asp

And some info on peony roses: http://www.burkesbackyard.com.au/1997/archives/27/in_the_garden/flowering_plants_and_shrubs/peonies
Happy gardening!

Don't feed the heather, they grow in acid impoverished soil and don't like their roots to sit in water.
Your Petunias, Fuchsias and Geraniums will bloom brighter and bigger for a good feed once the flowers are out. The Fuchsias and Geraniums will need to be taken in later in the year or the frost will kill 'em but the Petunias only last the year anyway.
